Castle Rock Estate winemaker Rob Diletti is something of a riesling specialist. This is one of three rieslings in the current range and is absolutely outstanding both in terms of quality and value-for-money. The Great Southern in Western Australia is a region that can compete with any in Australia in regard to riesling quality and potential longevity. Pale, but intense, this still quite tightly wound in its youth with lime and grapefruit juice notes to the fore. It has terrific structure and fresh zingy acid on the finish and is lip-smackingly good right now. Pair it with pan-fried whiting fillets.
